I would start with the power line conditioner. I've had great results with the Chang Lightspeed CLS6400 ISO then later I upgraded cords with Kimber PK 330 with wattagate plug to my Genesis Digital Lens (great improvement), then used MIT Z-Chord II H to CD transport, DAC and McCormack TLC-1 Deluxe passive preamp (great improvement). I also upgraded to a Chang CLS9600ISO and used 6400 for tv & dss. I would not use conditioner for power amp as my local dealer explained and I tried plugging my McCormack DNA-2 into conditioner and noticed loss of dynamics & pace (Audioquest AC-12 power cord (20amp iec) works great with amp) Good luck
Power Chords and Line Conditioning
Does a good power chord do the same thing as a line conditioner does? I hear in terms of performance that they both provide lower noise floors and with less hash and white noise. They tend to tighten up loose bass and smooth out the overall presentation of the signal. Just curious before I purchase either one of the two mentioned. Thanks
